Recently AMD quietly upgraded the EPYC 3000 series embedded processor, added EPYC 3255 model, 8 core 16 thread, TDP minimum 25W, up to 55W. AMD launched the EPYC 3000 series of processors in February 2018 for networking, industrial, storage, edge computing, and more.
Bloodline with the data center-oriented EPYC 7000 series of the same origin, with up to 16 core 32 threads, 32MB three-level cache, SoC on-chip system design (no additional chipset), support for four-channel DDR4-2666 memory, 64 PCI-E 3.0 bus, 8 10GbE Ethernet, 16 SATA or NVMe devices.
Security is also a top priority, integrating independent security subsystems that support encryption co-processing, hardware trusted root ( Root-of-Trust), SME/SEV memory encryption, and of course enterprise-class RAS features.
The EPYC 3000 series has up to 16 core 32 threads and is powerful enough for the embedded market.
AMD claims that the EPYC 3000 series is up to 2.7 times more cost-effective and twice more connected than its rival (the Xeon D Series).
Yesterday AMD quietly upgraded the EPYC 3000 series of embedded processors, first of all, the deletion of two product lines – EPYC 3401, EYPYC 3301 two 16-core, 12-core processors are no longer available.
The reason why AMD removed these two processors is unknown, and it is very close to EPYC 3451, EYC 3351 two processors positioning too close, there is no meaning.
While removing two products, AMD added a new model – EPYC 3255 processor, 8-core 16 thread, TDP 25-55W, frequency 2.5GHz to 3.1GHz, 16MB L3 cache, support for 2 channels OfD4-2666 memory, 32 PCIe channels, Operating temperatures from -40 to 105 degrees C.
From the EPYC 3255 processor, it significantly reduces TDP power consumption, up to 25W, but the frequency is the same as EPYC 3251, while the operating temperature range is greatly increased, previously ranged from 0-105 degrees C, that is, does not support low temperature environment work.
In addition, the EPYC 3000 series processor distinction is more obvious, EPYC 3451, EPYC 3351 two use SP4 slot, these two are dual-core architecture, while the other CPU uses SP4r2 slot, are single-core architecture, memory channels, PCIe and other IO numbers are cut in half.
The final price is still underpaid, it is not clear how much. Architecture, process is not mentioned, this should be the same as the 2018 EPYC release, there is no need to toss on the 7nm process.
